Hello,

I am trying to run a 3way coupled model (T2d, Tomawac, Sisyphe) on a Supercomputer using the Intel MPI.
The machine is based on CentOS.
When running the model in my local machine everything works fine, but it takes very long. When I start the model in the supercomputer I get the following error (see attached file).
What could be the reason for this behavior?
Is it even possible to run TELEMAC on a kind of this computer?

Leballeur OFFLINE openTELEMAC Guru Posts: 434 Thank you received: 163	Which test case did you try? and what is the error? As Pablo suggests, try first a T2D test case and then a coupled test case? Laurent

Leballeur OFFLINE openTELEMAC Guru Posts: 434 Thank you received: 163	and what is the error message when you try running it? in sequential and in parallel. No need to try a coupled test case while T2D alone is not ok. Did your compilation step well ended ? Laurent

Mustermann OFFLINE Expert Boarder Posts: 268 Thank you received: 4	Hi Laurent, I am not in charge for installations on the supercomputer so I can not tell if it went fine, but I assume so. Just got a message that they compiled it again using the intel compiler now the T2d testcase works without any issues. Therefor I would like to try a coupled one, could you recommend one?

Leballeur OFFLINE openTELEMAC Guru Posts: 434 Thank you received: 163	You can try "sandpit" for instance, for a coupling T2D-SIS. And then you can test the 3 way coupling with "littoral" test case. (in sisyphe example directory). Laurent

Mustermann OFFLINE Expert Boarder Posts: 268 Thank you received: 4	Hej Laurent, the testcases worked well but my case still does not work. Not sure why since it is running on my stationary machine without any issues. Attached is the stdout file. Would be great if you could take a look at it. Thanks a lot Regards, Clemens Attachments: out812061.txt (38KB)
